‘It’s very Instagrammable, for sure’: Balloon Museum opens in London

As my metre-tall daughter’s head slowly disappeared beneath the surface of a swimming pool filled with smiling yellow balls, I realised four-year-olds might not be the intended demographic of London’s latest interactive art exhibit. “Help!” she squealed, teetering between terrified and elated.

This enormous psychedelic ball pit takes centre stage at the Balloon Museum, which opened in east London on Wednesday. The concept began in Rome with Pop Air, before versions of the inflatable exhibition were exported around the world to 3 million visitors in cities including Paris and New York. Now it’s London’s turn with EmotionAir.
